Patent ES-345128-A1 (ES)
Title: Signalling system using time-division-multiplex
IPC: H04B1/68
Filed: 1967-09-16
Abstract: A plurality of channels carrying V.F. (e.g. dialling) signals are scanned in TDM manner and the results of the scanning are stored in a memory in respective sections thereof reserved for each channel. The contents of each section are then read-out at a much higher rate than they were written-in so as to effectively increase the frequency of the original VF signals whereby they can be analysed by BPF's having relatively large bandwidths and short transit times. This method is adopted because a centralized control analyzing the high frequency signals can monitor a greater number of channels carrying signals that last for a given time than could a control analysing directly the incoming VF signals. 2-out-of-6 VF signals having a minimum duration of 10 msecs. and occurring on channels S1 . . . Sn are sampled at a 5 kc/s. rate by scanner ZM and the results, after conversion into digital form, are stored in sections of a core store HSP pertaining to each channel. When each channel has been sampled 25 times scanning is stopped for one cycle and all the contents of HSP are read-out during this cycle, corresponding to a read-out rate of 5 Mc/s. Each section is read-out in parallel, via digital/ analogue converter DAW, low-pass filter TP (cut-off 5 Mc/s.) and band-pass filters BF1- BF6 (bandwidth 100 kc/s.), so that a 2 out-of-6 code is written into similar sections of a store (register) RSP. It is ensured that each code contains only two elements by means of a fault detector CU. If incoming signals occur in 2-out-of-8 code, they are analysed and then converted into 2-out-of-6 code by auxiliary filters BF1 and converter CW. The above numerical data relates to a system having 20 channels. If the incoming signals have a greater minimum duration then the channels can be arranged in groups and each group then scanned and analysed repeatedly but in turn (Fig. 4, not shown). It is mentioned that the various scanning operations may be controlled by a stored program.

Patent ES-360082-A1 (ES)
Title: Roller testing stand for motor vehicles
IPC: G01M17/007
Filed: 1968-11-11
Abstract: Apparatus for measuring the torque exerted by the wheels of a vehicle comprises a roller stand for locating the driving wheels of the vehicle, each roller having a tachogenerator, and an eddy current brake whose force is measured by the twist of a spring-loaded stator, whereby the pull required to maintain a desired speed or acceleration is determined. The frequency speed signals from four independent photo-electric tachogenerators 14a-d Fig. 1 associated with the left and right hand rollers 1-4, are converted to corresponding voltage amplitudes and combined to feed a speedometer. Rollers 1, 3 are each coupled to an eddy current brake 9 comprising a D. C. -energized stator and two rotors, one fixed to a shaft 7 of roller 1 and the other fixed to shaft 8 of roller 3. Rotation of the rollers drags the stator of brake 9 against a spring 11 through an angle proportional to the torque exerted by the brake and measured by rotary potentiometers 12, 13. The speed signal is differentiated to provide an accelerating force signal, which is added to the brake torque signal to determine the total pull exerted by the wheels. If the speed is maintained constant, the braking torque is equal to the pull of the wheels. To determine the effect of different road conditions, the stator of the eddy current brake 9 is energized, as shown in Fig. 5, by the sum of voltages comprising (a) a voltage U'p representing the torque of the brake, obtained from rotary potentiometer 13 coupled to the stator of the brake. (b) a voltage Ulw representing air resistance, obtained by squaring the speed signal Uvt and multiplying by factors representing the air resistance of the vehicle and the air density. (c) a voltage Uh representing the effect of ascending a slope, obtained by appropriate adjustment of the slider of a potentiometer 43 fed with a constant voltage 42. (d) a voltage Uak representing the additional force required for acceleration, obtained by differentiating the speed signal at 44, and multiplying it at 45 by a factor depending on the weight of the vehicle. The system may include a timing arrangement Fig. 6, (not shown) for measuring the time taken to change from one speed to another.
